Haven't had to do a full ride on here quite awhile! I had to today since my daughter decided to take a 3 1/2 hour nap and sleep through Jons lunch which would have been my only option outdoors today...oh well. My HR was way too low, never even got close to 140s which is normally my HR on a pretty easy effort. This bike felt like my usual 150s HR effort so need to talk to Nathan about this...possible overtraining sign?
